Ay, exciting na! Honestly, once you're 1cm dilated and may primrose na, it could be days or weeks pa, walang exact timeline kasi bawat mama different talaga, lalo na first time. A few of us tried primrose oil din and some went into labor within days, pero iba nag-take ng weeks pa before actual labor started, so really just depends on your body. Best talaga is check with your OB para ma-monitor kung paano exactly ang progress mo and makita if kailangan na ng next steps, kasi they'll have better idea based sa cervix check and contraction patterns mo. Rooting for you, mama!
